Abstract

The frequency and temperature dependence of the in-phase component of the ac-voltage generated by a constant amplitude ac-current was measured in the high-T_c copper oxide superconductors. The results clearly demonstrate the sensitivity of this method toccompositional and/or structural details of the system. The measurements were performed on YBa₂ (Cu_1-xM_x)₃O_7-y with M = Fe or Ga, both above and below T_c in the frequency range 0 to 30kHz. The data are analyzed in terms of a frequency power-law dependence of the ac-losses. The effects of magnetic and non-magnetic substitude ions are discussed.
